我将VS 2015与1.3 SDK一起更新到Update 2，现在当我打开一个xaml文件时，设计师似乎正在努力工作并挂起所有VS.当关闭显示有异常时，检查它显示的日志：
有任何解决方法吗？

当我创建一个新项目时，设计师工作正常，但我在Application选项卡上的项目属性上遇到以下错误：
属性访问者＆＃39; TargetDescriptions＆＃39; on object＆＃39; Microsoft.VisualStudio.ProjectFlavoring.Automation.Project.CommonProjectExtender＆＃39;抛出以下异常：＆＃39;值不能为空。
如果我保留最低版本10.0.10240或将min保留为10586
，则会发生这种情况删除SDK 10240有助于解决我的旧版＆＃34;中的设计师问题。项目，仍然是项目属性的错误发生
更新
我完全卸载了Windows 10 SDK以及8.1 SDK，然后使用开发者网站https://developer.microsoft.com/en-us/windows/downloads中的VS安装程序重新安装了10个SDK（10586）
现在情况更糟，我无法编译，属性中的应用程序选项卡现在说：
尝试加载页面时出错。 InvalidArgument =＆＃39; 0＆＃39;的值对于＆＃39; SelectedIndex＆＃39;无效。 参数名称：SelectedIndex
当我尝试创建一个新的Blank Universal应用程序时，我收到以下消息： ＆＃34;找不到合适的SDK来定位＆＃34;
答案 0 :(得分：1)
嗯，唯一可行的是卸载所有独立的Windows SDK，从10586.11,10586.15及之前，然后再重新安装10586.15，这最终有效，以防万一有人进入此
